../../lib/boost/boost/range/join.hpp:47:11: error: no type named 'type' in
'boost::range_detail::demote_iterator_traversal_tag<
boost::detail::iterator_category_with_traversal<
input_iterator_tag, boost::random_access_traversal_tag
>, boost::random_access_traversal_tag
>'

What is going on?

My implementation for calculating the minimum traversal is incomplete because it does not provide template specializations for the iterator_category_with_traversal class. I need to spend a little more time looking into the best solution. A quick work-around would be to add the appropriate specialization. I am concerned that this might be a special-case of a more general issue with my code. I'll look into this more this week.

Thanks,
Nate.

Thank you for bringing this to my attention.
